README

Slick/Validator is a set of input validation tools that can be used to check your input data. It also has the concept of Validation Chain that can combine validators for a specific validation.

This package is compliant with PSR-2 code standards and PSR-4 autoload standards. It also applies the semantic version 2.0.0 specification.

Install

Via Composer

$ composer require slick/validator

Usage

One of the easiest ways of using a validator is using StaticValidator class to check a value:

use Slick\Validator\StaticValidator;

if (StaticValidator::validates('notEmpty', $value) {
  // Some code with valid value
} else {
  print StaticValidator::getMessage(); // Print out validation messages
}

Slick/Validator comes with the following validators:

StaticValidator is also a validator objects factory. For example:

use Slick\Validator\StaticValidator;

$urlValidator = StaticValidator::create('notEmpty', 'You must enter a valid URL.');

if ($urlValidator->validates($_POST['url']) {
    // URL is valid use it...
} else {
    print $urlValidator->getMessage(); // Will print out 'You must enter a valid URL.'
}

Combining various validator to use it as a single validation can be done with ValidationChain.

use Slick\Validator\StaticValidator;
use Slick\Validator\ValidationChain;

$emailValidation = new ValidationChain();
$emailValidation
    ->add(StaticValidator::create('notEmpty', 'Email address cannot be empty.'))
    ->add(StaticValidator::create('email', 'The entered e-mail is not a valid address.');
    
if ($emailValidation->validates($_POST['email']) {
    // URL is valid use it...
} else {
    print implode(', ', $emailValidation->getMessages()); 
    // Will print out the validation messages for the validator(s) that fail.
}

You can always create your own validator and use the StaticValidator or the ValidationChain as long as you implement the Slick\Validator\ValidatorInterface or Slick\Validator\ValidationChainInterface.
